  • Length: 6–12 meters (standard or custom-cut) .
• Surface Treatment: Hot-dip galvanized, 3LPE coated, or varnished for corrosion resistance in harsh environments .

Core Features

1. Low-Temperature Performance: Enhanced notch toughness (≥34 J at -20°C) ensures structural integrity in sub-zero environments, ideal for LNG pipelines and cryogenic storage .
2. High Pressure Resistance: Suitable for systems operating up to 60 MPa, including boilers, heat exchangers, and steam lines .
3. Seamless Construction: Eliminates weld seams, reducing weak points and ensuring uniform strength for bending, flanging, and high-stress applications .
4. Corrosion Resistance: Galvanized or epoxy coatings extend service life to 20+ years in marine, chemical, and industrial settings .
5. Certified Quality: Compliant with ISO 9001, CE, and ASME B36.10M standards, supported by mill test reports (EN 10204 3.1/3.2) .
